Right on cue, it's time to subsidize drivers at non-drivers expense again, as is tradition.

The way the press is treating chatbots, like they have agency and they β€œknow” things all of a sudden, crossed the line recently from dumb and obsequious to something else entirely. Treating them as alive and making conscious decisions is an almost religious belief. It won’t age well.

Why are famous chefs fighting PFAS bans? The answer, in retrospect, is obviousβ€”and it’s part of a larger campaign to stop bans on Teflon cookware nationwide.

Celebrity chefs told Californians that PFAS-coated pans were β€œsafe,” and successfully lobbied Gavin Newsom to veto a bill phasing them out

They didn’t mention they all sell PFAS-coated pans.

New joint investigation with @mirandagreen.bsky.social and @atmosmag.bsky.social is out:

Top researchers consider leaving U.S. amid funding cuts: 'The science world is ending'
Top researchers consider leaving U.S. amid funding cuts: 'The science world is ending' YouTube video by PBS NewsHour

The United States was the leading destination for top scientists from all over the world.

That is ending. Politicians ended it. It will cripple our future competitiveness.

And it’s such a bitter tragedy. Almost no Americans, Conservative or Liberal, grasp what is now being stolen from them.

Artists are losing work, wages, and hope as bosses and clients embrace AI Visual artists, illustrators and graphic designers share their stories about how AI is being used to lower wages, degrade work and even replace it altogether, in this installment of AI Killed My Job.

Freelance illustration gigs drying up. Ad agencies using Midjourney instead of hiring human artists. Costume design turned over to AI wholesale. Good work vanishing.

These are the stories of working visual artists, who describe losing jobs, wages, and hope as their clients and bosses embrace AI.

In this blog post, I use #RStats to analyze ICE detention data. #Datavisualization shows record numbers of detainees without any criminal records. Further more/bigger ICE facilities are popping up far from the border.

Because no one spends as much on science as the US does, destroying NIH, NSF, NOAA, NASA, EPA, USDA, USGS, etc. is leading to a brain drain, but it's not to other countries but rather from science. This senseless destruction of US science will hurt the US and the world for a very long time.

We need to build some real social stigma around being afraid of cities. You don't have to like them or live there, but a politics built this strongly around watching TV and going "ewww" is embarrassing, and people should be embarrassed by it. It's like "fear of werewolves" being your top issue.

US science is being wrecked, and its leadership is fighting the last war Facing an extreme budget, the National Academies hosted an event that ignored it.

The failure of the National Academy of Sciences USA to make a clear and unequivocal statement about the disastrous Trump administration science policies β€” it lets all of us down and dooms them to eventual irrelevance.

β€œI Have Lost Everything”: The Toll of Cities’ Homeless Sweeps Cities often take belongings β€” including important documents and irreplaceable mementos β€” when they conduct sweeps of homeless encampments. ProPublica gave notecards to people across the country so…

We asked people who lived in homeless encampments that were cleared out in city β€œsweeps” to write about what object was the hardest for them to lose.

β€œThey took my baby pictures and my moms obituaries,” a 29-year-old in California wrote.

It could be related to that, and I do think the top two are REALLY good. But I think it's also related to the Valkyries starting out at 1300, which brings the league average down a bit.
